We have deployed a 2012 R2 RDS Farm with RemoteApp(s) published via RDWEB but have encountered an issue with Outlook.
The application launches and operates correctly but when the users are required to authenticate with the Exchange Server the credentials dialogue window is not visible.
If I access Outlook via an RDP session directly on the server desktop, the credentials box pops up and can be populated accordingly.
It appears that when Outlook is launched as a RemoteApp the credentials popup window is hidden/no visible.
Has anyone else encountered this issue?
